IMPROVEMENT IN MODE 0F WEAVING FABRICS WITH BUTTON-HOLES THEREIN.

Specilication forming part of Letters Patent No. 47, |51, dated April 4,1865.

To all whom t may concern:

Be it known that I, JOHN UoNNoR, a subject of- Great Britain, residingat Boston, county of Suffolk, and State of Massachusetts, have inventeda new and useful Improvement in Weaving; and I do hereby declare thatthe following, taken in connection with the drawings which accompany andform part of this specification, is a description of my inventionsufficient to enable those skilled in the art to practice it.

This invention relates to the weaving of fabrics containing or tocontain button or similar holes, said holes being formed by or in theprocess of weaving, and the principal object of the invention is toweave narrow fabrics-such as suspender-webbing, &c.- with button-holes.

The invention consists in the employment of a peculiarly-shaped reed,which, by having imparted to it a vertical movement, in connection withthe ordinary beat of the lay and the interruption of the take-up, sodisposes the shoot as to weave the second side of the button-hole, orthe fabricforming such side, as will be fully described.

Figure l of the drawings represents a perspective view, and Fig. 2 aside elevation, of a reed embodying my construction. Fig. 3 shows amodification of the same.

a denotes the frame of the reed, I) the dents upon one half, and c thoseupon the other half of the same. The dents b are made of the usual form,while each dent c is constructed or provided with a projection, d, saidprojection having at one end a width, e f, equal to the length of thehole to be formed in the cloth, and joining the dent atg, as seen inFig. l. The dents b and c correspond with each other, excepting withrespect to these projections. The rear side of the reed-frame isprovided with a rack, h, by which, through a gear-wheel upon a shaftconnecting with the mechanism which drives the loom, a vertical motionmay be imparted to the reed.

The operation of the reed is as follows Suppose A to represent a pieceof suspenderwebbing being woven upon the loom, while the part whereinthe woof or shoot extends entirely across the cloth is being made, thewarp-threads extend through the dents above the point g or where thebeating-faces of the dents are all on the sameline, and the shoot is ofcourse thrown through all the warpthreads or the shed is made across thewhole width of the webbing. As the point t' is reached, where thebutton-hole is to commence, the shed is made only with that halt of thethreads extending through the dents b, and the effect is to weave thepiece 7c. As this operation commences an upward movement is given to thereed, and continued at each beatup of the lay, the movement being tosuch extent that wh en the desired length is woven at k for thebutton-hole the Widest part of the projections d (or the parts thereofhaving a width equal to the length given to the piece lc) shall haverisen to the plane of the cloth. While the piece 7c is being woven thecloth is taken up by the clothbeam as usual. The take-up is then stoppedand the shed made only by the warp-threads running through the dents c.Now, it will be evident that the first shoot thrown through the shed bythe shuttle will be beat by the projections d close up against the lastthread o o, extending entirely across the warp. At the next beat of thelay a downward movement is given to the reed, so that the shoot beat upthereby is driven a little less distance in than the last, or, in otherwords, up closely against the previous shoot, and so on, the reeddescending at each beat as the shoot approaches nearer and nearer to theend of the buttonhole. When alength equal to the piece k is thus woventhe take-up is again applied, the vertical movement of the reedarrested, the shed madein the whole Warp, when the weaving will continueas at first, leaving the button-hole formed, as will be readilyunderstood.

Instead of giving both an up-and-down movement to the reed, the weavingof the part k may be carried on near the line .r or just below thewidest part of the projections d, so that when the part la shall havebeen woven the reed shall be in position by a slight downward movementto commence beating the shoot up against the other half, the verticaldownward movement of the reed being then continued until the pieceopposite to the part k is woven, the same as above described. In thiscase, however, the reed, after the buttonhole is thus formed, will haveto be raised the the dents d to bring the part below length of alwaysthe same, while by constructing it as described and giving to itvertical movements, in combination With forming a shed upon one side ofthe webbing at a time and arresting the take-up motion when the secondpart orV side of the hole is being formed, the process is rendered morecertain and practicable than by these other methods.

l claimr:Ehe improvement in Weaving suspender- Webbin g, 85e., to formbutton or other similar holes therein by the employment of a reed havinga construction and operating in the manner substantially as set forth.

In witness whereof I have hereunto set my hand this 21st day ofNovember, A. D. 1864.

JOHN CONNOR.
